5.2.3.3 Adjusting the image temperature
In the Image menu, touch the icon “ ” to set the adjusting mode of the temperature
associated with the image framed on the display. The following options are available:
 Automatic (Auto) mode  the minimum and maximum temperature levels of the
framed object on the display and associated with the colour palette are automatically
defined by the instrument and dynamically vary when moving it. This (default) option,
which can be used in most cases, allows for an optimum display of the IR image in a
condition of temperatures equally distributed within it.
 Histogram (HG) mode  the minimum and maximum temperature levels of the object
framed on the display are always defined automatically by the instrument, as in Auto
mode, but in this case, the areas of the image in which temperature values are very
different from the values of adjacent areas are highlighted.
 Manual (M) mode  the minimum and maximum temperature levels of the object
framed on the display are manually set by the user, who can associate, if necessary, a
custom colour palette. This mode, particularly useful to clearly identify only some areas
of the image, is recommended in case of advanced thermographic operations.
1. Touch the symbols “<” and “>” to set the Automatic or Histogram modes. The following
screens are shown on the display: The messages “Auto” and “HG” are found in the
lower part of the colour palette.
